WHY ARE WE PAYING TO COOL OUR HOUSE IN WINTER?

hydro metre

It’s minus 5 degrees outside but inside the house it’s warm and comfortable.  If your like most people, as the furnace is running to warm your house the hydro metre is running extra fast powering compressors to keep the inside of the fridge and freezer cold.  In climates that are often below the freezing mark 4-5 months out of the year why not use the outside elements for cooling?

By installing a temperature exchange unit similar to a car radiator outside (photo above)  and a smaller one inside the fridge it should be possible on cold days to use a very low energy water pump to circulate plumbing antifreeze through insulated pipes between the two.  The circulating water pump would use a small fraction of the energy of the fridges compressor and if used 4 months out of the year should not only save money on energy but also extend the life of the appliance by 33%.

When the outside thermostat registers -5 degrees or colder a signal is sent to the control module inside the fridge and a relay disconnects the fridges compressor.  Instead of the fridges thermostat activating the compressor when it becomes too warm the pump is activated instead and cold plumbing antifreeze from the “outside temperature exchange unit” is brought through insulated pipes to the “fridge temperature exchange unit” and cools the fridge.  When the fridge is cold again the control module shuts off the pump.

On a commercial level such as in a supermarket with rows of freezers, using the outside cold from the winter has a much bigger benefit.  Cooling tubes mounted in the freezer during manufacturing could be used in winter to circulate cold plumbing antifreeze from outside storage reservoirs.   Conventional cooling compressors would still be used for summer time or warm winter days.

Another possibility is on cold winter days would be to use cold air instead of cold liquid.

A thermostat in the food cooler from a grocery store would activate a roof vent fan.  Cold outside air would be blown down through insulated ducts to the inside walls of the food cooler.

In winter, the insulation from the inside walls of the food cooler would be automatically retracted creating a channel for cold outside air to be blown through.

WINTER POSITION MONK REDUCED

In summer time the insulation is automatically moved up against the inside walls of the food cooler. A traditional compressor is used with evaporator coils.

Its hard to believe that in todays day and age we still waste so much energy and money creating a cold area for food when in the winter time our house is surrounded by it.

CONTROLLING THE SPREAD OF CAT LITTER

FINAL good

Anyone that owns a cat knows one of the biggest problems is the cat litter.  Aside from the smell, bits of litter stuck to the cat’s paws as it leaves the litter box end up end up all over the floor.  Unless swept up constantly they quickly get tracked everywhere.

I have found that placing an old car floor mat in front of the area the cat uses to exit the box  that 90% of the litter gets trapped in the groves of the mat reducing the need to sweep the floor as often.

Most cats take a while to get used to walking on the mat so at first you will most likely have to block off 3 sides of the litter box with something high so they have to exit to the one side that has the mat in front.  Once they are used to the mat, cutting a grove to make one side of the litter box lower will encourage them to use that side and step on the mat as they exit.

GET THE PULLING POWER OF A 4 X 4

WINCH 1

Bolt a 12 volt, 3000lb winch onto a trailer coupler and attach it to the trailer hitch of any vehicle and for around a $100.00 you now have the power to move heavy loads short distances.

I recently bought a boat and trailer in late fall that I needed to get into a tight spot for winter storage.  A regular size vehicle was too big and my small lawn tractor had no where near the power to move it, so I built this device  to attach to the lawn tractor’s trailer hitch.  By having someone hold the brakes down on the lawn tractor and blocking the wheels, with the engine turned off and the transmission in neutral, I was able to move the boat to where I wanted it by just using the winch.

When it came time to take the boat out of the water the 2 wheel drive pickup I was using could not get enough traction on the launch ramp to pull the weight of the boat and trailer up it.  I had this device with me so I parked my Cavalier at the top of the ramp on level ground.  I attached this device onto the trailer hitch of the car and connected the hook to the front bumper of the pickup.  I then had someone start the car (so the power brakes would be working), put there foot firmly on the brake (preventing all 4 wheels from turning) and place the car in neutral (to prevent damage to the transmission).  I was then able to use the winch to pull the pickup, boat, and trailer up the launch ramp.

There is no telling how many uses a device like this could be good for.  Next spring I am going to use it to try to remove an old tree stump.

SAVING ENERGY WITH SMART BLINDS & RADIANT HEAT / INVENTION IDEA

SMART BLINDIf you have a large window in your house that gets a lot of sun, whether the blinds are open or closed through out the day could make a significant difference in your heating and cooling energy costs.

The photo below shows the difference in temperature inside and outside a parked car in the winter. The temperature inside the car is about 20 degrees Celsius warmer then outside.

What if your blinds worked automatically to take advantage of this heat energy.  In the winter time when the sun was shinning through the window the blinds would open to use the radiant heat from the sun to help heat the house and at night or when it was cloudy the blinds would close to help insulate from the outside cold.

We all know how much heat can build up in a car in the summer and the same goes for your house if the sun is shining in. In the summer time the blinds would do the opposite. When the sun was shining through the window the blinds would close keeping the house cooler and saving on air conditioning costs.

Only when direct sunlight comes in contact with the solar cell would the circuit board activate the motor.  When the 3 way switch was set to winter the blinds would open but when there is no direct sunlight making contact with the solar cell the blinds would close.  When the switch is in the manual position the power is disconnected to the motor and the blinds remain in what ever position they are set.  When set for summer the blinds would close whenever direct sunlight comes in contact with the solar cell.  The solar cell would also keep the 2 x “AA”  rechargeable batteries charged.
